Make sure that we add the appropriate rpaths so that the appropriate
_Concurrency back-deployment library can be picked up.
We don't need to update the Swift driver since it uses the C++ driver
as the source of truth to determine if the relevant rpath should be
added or not.
To allow us to start testing language changes tied to a future Swift 6 mode without actually *shipping* a Swift 6 mode to customers who might accidentally use it before it's ready.
This commit also adds parallel tests for a number of already existing (but untested) Swift 6 mode behaviors.

Introduce a second level of standard substitutions to the mangling,
all of the form `Sc<character>`, and use it to provide standard
substitutions for most of the _Concurrency types.
This is a precursor to rdar://78269642 and a good mangling-size
optimization in its own right.
This will allow teams writing access notes to use -Raccess-note=all-validate to check that their access notes are correct, or teams working around problems to use -Raccess-note=failures or -Raccess-note=none to suppress diagnostics.
The locations stored in .swiftsourceinfo included the presumed file,
line, and column. When a location is requested it would read these, open
the external file, create a line map, and find the offset corresponding
to that line/column.
The offset is known during serialization though, so output it as well to
avoid having to read the file and generate the line map.
Since the serialized location is returned from `Decl::getLoc()`, it
should not be the presumed location. Instead, also output the line
directives so that the presumed location can be built as per normal
locations.
Finally, move the cache out of `Decl` and into `ASTContext`, since very
few declarations will actually have their locations deserialized. Make
sure to actually write to that cache so it's used - the old cache was
never written to.
The triple name aarch64_32 does not actually name a valid platform. The
actual platform (and valid triple arch string, confusingly enough) is
arm64_32. Remap between the two to correct for this difference.

Commit the platform definition and build script work necessary to
cross-compile for arm64_32.
arm64_32 is a variant of AARCH64 that supports an ILP32 architecture.
This commit fixes two weird bugs in -verify mode:
1. SourceLocs from the wrong SourceManager could be passed through a ForwardingDiagnosticConsumer into the DiagnosticVerifier.
2. -verify-additional-file did not error out correctly when the file couldn’t be opened.
No tests, as we only have basic tests for the diagnostic verifier.
The frontend supports this via new options -index-unit-output-path and
-index-unit-output-path-filelist that mirror -o and -output-filelist. These are
intended to allow sharing index data across builds in separate directories (so
different -o values) that are otherwise equivalent as far as the index data is
concerned (e.g. an ASAN build and a non-ASAN build) by supplying the same
-index-unit-output-path for both.
This change updates the driver to add these new options to the frontend
invocation 1) when a new "index-unit-output-path" entry is specified for one
or more input files in the -output-file-map json or 2) if -index-file is
specified, when a new -index-unit-output-path driver option is passed.
